Grinders are the most confusing category of submersible pumps. Even seasoned professionals ask for a "Grinder." when what is needed is a lower head, lower cost sewage pump.

A grinder is typically a higher-powered (1HP and greater) pump fitted with sharp cutters to shread solids and move them under high pressure usually in a relatively small diameter pipe. Grinders are most commonly used for lower flows and high pressure or higher head applications. As an example, a grinder is normally used when pumping into a pressure sewer system.

The typical residential 2 HP Grinder Pump, can pump 40 GPM @ 20' of head. It may have internal capacitors or a control anel may be required.  Better grinders have triple-seals non-wicking cord design, are grit-resistant, smf and have silicon carbide seals and, even a secondary lip seal for added protection.  Most have stainless steel cutler assembly and effectively grinds domestic sewage into a fie slurry, heavy-duty upper and lower ball bearing cutter assembly , hardened 440c stainless steel (56-60 Rockwell C) shredding ring and grinding impeller, 8300 cuts per second - 1/2 Million cuts per minute impeller, ductile iron for  long life, recessed (Vortex) design reduces bearing load / increases bearing life and prevents clogging, full mechanical seal (Silicone/Carbide) and secondary lip seal, capacitor start/run design internal,
